MCQ Companion to
Applied Radiological Anatomy
This helpful revision aid will be of great practical beneﬁt to all trainees in radiology,
including those studying the new modular curriculum for Fellowship of the Royal
College of Radiologists Part 2A examination. The carefully structured questions and
answers enable the trainees to undertake a systematic assessment of their
knowledge, as well as highlighting areas where additional revision is required. This
publication has been designed to complement its highly illustrated companion
volume Applied Radiological Anatomy (by Butler, Mitchell & Ellis), which itself
serves as a comprehensive overview of anatomy as illustrated by the full range of
modern radiological procedures. Both books can be used independently of one
another; however, it is anticipated that the trainee will gain maximum beneﬁt from
using the two books together. Although allied closely to the curriculum for the new
radiology exam, the choice of questions will be relevant and useful for radiology

It is a pleasure to write a Foreword to this book of MCQs. Sometimes an
‘accompanying volume’ is a poor relation of the original; not this one – it
made me thirst to go to the excellent original to check and recheck my
It is also pleasing to see an MCQ book entirely devoted to radiological
anatomy. Many medical schools are currently reducing the content of their
anatomy (morphology, architecture, etc.) courses, given perceived
overloading of the curriculum. Thus future radiological trainees may have
less background anatomical knowledge than their predecessors. Radiology
depends entirely on being able to recognise normal anatomy, anatomical
variants thereof and abnormal structures. Indeed, detailed knowledge of
anatomy and applied techniques is usually the deciding characteristic
among radiologists and clinicians with an interest in imaging. It behoves all
radiologists to learn anatomy in depth and to maintain and develop that
knowledge throughout their professional career.
This book also serves as a reminder to examination candidates (and
examiners) that anatomical questions are still very much in vogue within
the new Royal College of Radiologists’ examination scheme. This book
jumps ahead so that the questions are grouped together in system-based
modules: a forerunner of things to come.
Setting MCQs is no easy task. The authors have done a good job to make
them relevant and realistic for examination purposes. Of course, there will
be one or two minor quibbles when the book is reviewed and most
statements including ‘may’ are true! However, this is not the point. This is a
revision (or in some cases a vision) for those working to attain a certain
standard of radiological anatomical knowledge. To this end, this slim
volume will be an enormous help and even makes for an amusing brain
exercise for more senior citizens. I congratulate the authors and hope that
the book gains the success it deserves.

One of the best ways to prepare well for an MCQ exam is to make up MCQs
whilst reading a text. This book is the result of such an eﬀort for the
Fellowship of the Royal College of Radiologists (FRCR) 1 exam with the
textbook Applied Radiological Anatomy.
The Royal College of Radiologists recently introduced the modular exam
for the FRCR 2A. The radiological anatomy, techniques and physics will
contribute about 15–20% of all the MCQs. The purpose of this work is to
present questions on radiological anatomy for the six modules of the FRCR
2A. Therefore, the book is presented as six modules, each representing a
module for the FRCR 2A. The modules should be read in conjunction with
chapters in the textbook Applied Radiological Anatomy. The questions with
the relevant answers are on opposite pages which makes easy reading.
Some questions are based on pathology and some are related to general
radiological technique from day-to-day practice. It is hoped that this will be
stimulating to the trainee and help with better understanding in acquiring
the general skills of performing and reporting radiological examinations.
We have not included a separate module on surface anatomy. However,
questions on relevant surface anatomy are included in the various
modules. Some of the chapters from Applied Radiological Anatomy have
been included in a related module. For example, the chapter on renal tract
and retroperitoneum and pelvis has been included in Module 4.
It is hoped that this book will provide radiology trainees with a focused
approach to learning MCQs from diﬀerent anatomical locations and
prepare them well for the modules of the FRCR 2A.

lateral radiographs. It separates the lingular segments from the rest of the upper
(e) False – they are pleural reﬂections that hang down from the hila and from the
mediastinal surface of each lower lobe to the mediastinum and to the medial
part of the diaphragm.

(e) False – inserts into the iliotibial tract – a strong thickened band of deep fascia of
the lateral aspect of the thigh (fascia lata) which is attached to the lateral
condyle of the tibia.

intercondylar fossa of the upper end of the tibia is used to detect intra-articular
opacities. These opacities are ‘loose’ bodies if they change position.
(b) False – the lateral femoral condyle projects more anteriorly and tends to prevent
(c) True – has a high correlation with a tibial plateau fracture – probably the most
commonly missed fracture of the knee.
(e) False – the vein is superﬁcial to the artery. Hence during Doppler ultrasound for
venous thrombosis, excess pressure with the probe will obliterate the lumen
and it cannot be visualized. This applies to ultrasound of veins in general.
However, this is a sign to be elicited with the probe held transverse to the vein,
to ensure patency of veins.

longitudinal to the long axis of the metatarsal.
45 Module 2: Musculoskeletal and soft tissue
(b) False – strongest tendon, but no sheath, therefore tenosynovitis does not accur.
(c) False – this is the tibialis posterior which provides support to the longitudinal
arch. Problems in the arch can lead to tendonitis or even rupture usually just at
or above the tibiotalar joint.
(d) False – the mnemonic Tom (tibialis posterior), Dick (ﬂexor digitorum longus),
and (posterior tibial vessels and nerve), Harry (ﬂexor hallucis longus) is helpful
in remembering the relations of these important structures at the level of the
ankle joint from medial to the poserto-lateral aspect.
(e) False – talus has no muscle attachment. The tibialis posterior inserts into the
navicular, and gives variable slips to tarsal bodies and bases of second, third
and fourth metatarsals.

anterior and posterior tibial and ﬁbular ligaments. The anterior taloﬁbular
ligament is the most commonly torn ligament in the ankle.
(d) True – in the sinus tarsi syndrome this fat is obliterated with disruption of the

bony, cartilagenous or ﬁbrous, most commonly occurs at the calcaneo-
navicular joint and is usually bilateral.
(a) True – an angle less than 20° indicates ﬂattening of the calcaneum due to crush
injuries resulting from jumping on to a hard surface from a height.
(b) False – CT, particularly in the coronal plane, is the best way of looking at the
(c) False – tendons are echobright. Echopoor areas in the tendon may be due to
tendonitis and a gap in the tendon is diagnostic of a tear.
(d) True – in the oblique view of the foot, the medial margin of the base of the third
metatarsal should be in line with the medial margin of the lateral cuneiform. If
not, it is a Lisfranc injury.
(e) False – avulsion fracture of the base of the ﬁfth metatarsal is transverse to the
long axis of the metatarsal. An apophysis which mimics a fracture is
longitudinal to the long axis of the metatarsal.
